The effects of logotherapy on meaning in life and quality of life of late adolescents with terminal cancer

Purpose: To evaluate the effects of a logotherapy program entitled 'Finding meaning in my life' for adolescents with terminal cancer. Methods: A nonequivalent control group, non-synchronized design was conducted with a convenience sample of 44 late adolescents with terminal cancer. The experimental group (n=22) participated in the 'Finding meaning in my life' program which consisted of five-day sessions for one week. The control group (n=22) received the usual nursing care. The effects were measured using adolescent meaning in life (AMIL), and quality of life (QOL) scales. The collected data were analyzed by descriptive statistics, Chi-square, and t-test using SPSS/PC 17.0 program. Results: There were significant differences in AMIL (t=3.36, p<.05) and QOL (t=2.67, p<.05) between the experimental and control groups. Conclusion: Logotherapy is effective in improving the meaning in life and quality of life of late adolescents with terminal cancer, and can be used to prevent existential distress

Primary Osteosarcoma in Patients Older than 40 Years of Age

Among the 665 patients who registered at our hospital, we reviewed 39 cases of high grade primary osteosarcoma in patients who were older than 40 yr of age. The aim of this study was to determine if a primary osteosarcoma in older patients has different clinical features, and a poorer prognosis than in younger patients. Two evaluations were performed. In the first, an attempt was made to determine the possible prognostic factors such as gender, location, size, alkaline phosphatase, radiological findings, chemotherapy intensity, chemotherapy-induced tumor necrosis, and surgical margin. The second evaluation involved assessment of whether there were any significant clinical differences between older patients and adolescents. According to the results, a primary osteosarcoma in older patients did not reveal any significant prognostic variables. A primary osteosarcoma in older patients showed a poorer prognosis due to relatively unusual locations, common abnormal radiological findings, and a poor response to chemotherapy. Therefore, careful attention should be paid to making an accurate diagnosis and new strategies for more effective treatment, including chemotherapy, must to be developed in order to achieve long term survival in older patients with osteosarcoma

Safety, tolerability of ES16001, a novel varicella zoster virus reactivation inhibitor, in healthy adults

Purpose Herpes zoster (HZ), or shingles, is a clinical syndrome resulting from the reactivation of latent varicella zoster virus (VZV) within the sensory ganglia. We evaluated the safety and tolerability of ES16001 (ethanol extract of Elaeocarpus sylvestris var. ellipticus), a novel inhibitor of varicella zoster virus reactivation in healthy adults. Method Single-center, randomized, double-blind, placebo-controlled, single and multiple ascending dose (SAD and MAD, respectively) studies were conducted in 20- to 45-year-old healthy adults without chronic disease. In the SAD study (n = 32), subjects randomly received a single oral dose of 240, 480, 960, or 1440 mg ES16001 or a placebo. In the MAD study (n = 16), subjects randomly received once daily doses of 480 or 960 mg ES16001 or a placebo for 5 days. The safety and tolerability of the drug were evaluated by monitoring participants treatment emergent adverse events (TEAEs) and vital signs, electrocardiograms (ECGs), physical examinations, and clinical laboratory tests. Results In the SAD study, 11 adverse reactions were seen in 5 subjects, and in the MAD study, 8 adverse reactions were seen in 6 subjects. All adverse reactions were mild, and no serious adverse reactions occurred. The most common adverse reaction was an increase in alanine aminotransferase (ALT), but all test values were in the clinically non-significant range, and their clinical significance was judged to be small considering the fact that most of the test values returned to normal immediately after the end of drug administration. Conclusion ES16001 has good safety and tolerability when administered both once and repeatedly to healthy subjects. Further research is needed to identify any possible drug-induced hepatotoxicity, which appears infrequently. Our findings provide a rationale for further clinical investigations of ES16001 for the prevention of HZ. Trial registration: CRIS, KCT0006066.

The prognostic factors of recurrent GCT: A cooperative study by the Eastern Asian Musculoskeletal Oncology Group

Background Giant-cell tumor (GCT) of bone is a common primary benign tumor with high local recurrence and potential distant metastasis or malignant transformation. We haveinvestigated the clinical behavior of recurrent GCT of bone in the extremities. Methods We retrospectively reviewed 110 patients with recurrent GCTs of bone in the extremities treated by the Eastern Asian Musculoskeletal Oncology Group. The factors that affected the number of recurrences and distant metastasis were analyzed. Results The median interval between initial surgery and the first recurrence of GCTwas 16 months (2-180 months). All patients received additional surgery for first recurrence. Twenty-five patients had a second recurrence and 6 patients had a third recurrence. The mean interval between theinitial surgery and the first recurrence correlated withthe eventual number of recurrences-14.1 months for the repeated recurrence groups (two and three recurrences) and 28.3 months for the single recurrence group (p = 0.016). Campanacci grade did not correlate with repeated recurrence (p = 0. 446). The venue of the initial surgery did not correlate with recurrence but did affect preservation of the adjacent joint (chi-squared test; p =0.046). Campanacci grade II and III also correlated withsacrifice of the adjacent joint (p = 0.020). The incidence of lung metastasis and malignant transformation were 7.5% (8 out of 107 patients) and 2.7% (3 out of 110 patients), respectively. Repeat recurrence was associated with lung metastasis (p = 0.018). © The Japanese Orthopaedic Association 2011

Ultraviolet nanoimprinted polymer nanostructure for organic light emitting diode application

Light extraction efficiency of a conventional organic light emitting diode (OLED) remains limited to approximately 20% as most of the emission is trapped in the waveguide and glass modes. An etchless simple method was developed to fabricate two-dimensional nanostructures on glass substrate directly by using ultraviolet (UV) curable polymer resin and UV nanoimprint lithography in order to improve output coupling efficiency of OLEDs. The enhancement of the light extraction was predicted by the three-dimensional finite difference time domain method. OLEDs integrated on nanoimprinted substrates enhanced electroluminance intensity by up to 50% compared to the conventional device

Acetic acid-indigo carmine chromoendoscopy for delineating early gastric cancers: its usefulness according to histological type

<p>Abstract</p> <p>Background</p> <p>Endoscopic treatments, such as endoscopic submucosal dissection (ESD) and laparoscopic gastrectomy, are increasingly used to treat a subset of patients with early gastric cancer (EGC). To achieve successful outcomes, it is very important to accurately determine the lateral extent of the tumor. Therefore, we investigated the diagnostic performance of chromoendoscopy using indigo carmine dye added to acetic acid (AI chromoendoscopy) in delineating differentiated or undifferentiated adenocarcinomas in patients with EGC.</p> <p>Methods</p> <p>We prospectively included 151 lesions of 141 patients that had an endoscopic diagnosis of EGC. All the lesions were examined by conventional endoscopy and AI chromoendoscopy before ESD or laparoscopic gastrectomy. The border clarification between the lesion and the normal mucosa was classified as distinct or indistinct before and after AI chromoendoscopy.</p> <p>Results</p> <p>The borders of the lesions were distinct in 66.9% (101/151) with conventional endoscopy and in 84.1% (127/151) with AI chromoendoscopy (<it>P </it>< 0.001). Compared with conventional endoscopy, AI chromoendoscopy clarified the border in a significantly higher percentage of differentiated adenocarcinomas (74/108 [68.5%] vs 97/108 [89.8%], respectively, <it>P </it>< 0.001). However, the border clarification rate for undifferentiated adenocarcinomas did not differ between conventional endoscopy and AI chromoendoscopy (27/43 [62.8%] vs 30/43 [70.0%], respectively, <it>P </it>= 0.494).</p> <p>Conclusions</p> <p>AI chromoendoscopy is useful in determining the lateral extent of EGCs. However, its usefulness is reduced in undifferentiated adenocarcinomas.</p
